The man accused of killing Iowa State student-athlete Celia Barquin Arozamena wants to be tried at a later date.

In court documents filed Thursday, 22-year-old Collin Richards signed a waiver for speedy trial and asked the court to set a trial date in September or October.

He was originally scheduled to go to trial in April.

Richards was arrested back in September of last year and charged with murdering the former champion golfer for Iowa State at the Coldwater Golf Links in Ames.

He was living at a nearby homeless camp at the time of the murder.
